A control system is disclosed for controlling a power takeoff (PTO) shaft of a work vehicle (e.g., a tractor). The work vehicle includes an engine and an operator station, and the PTO shaft transfers power from the engine to an implement. The control system includes a remote switch, a vehicle speed sensor, and a control circuit. The remote switch is located remotely from the operator station and provides a remote switch signal to the control circuit to engage and disengage rotational movement of the PTO shaft. The vehicle speed sensor provides a vehicle speed signal to the control circuit representative of a speed of the work vehicle. The control circuit receives the remote switch signal and the vehicle speed signal and, when the vehicle speed signal exceeds a predetermined vehicle speed, the control circuit prevents engagement and disengagement of the PTO shaft with the remote switch.
A method of controlling a power takeoff shaft of a work vehicle, the work vehicle having an operator station, the method comprising:
A system for controlling the power takeoff shaft of a work vehicle, the work vehicle having an operator station, comprising:
A control system for controlling a power takeoff shaft of a work vehicle, the work vehicle having an operator station, the control system comprising:
A control system for controlling a power takeoff shaft of a work vehicle, the work vehicle having an operator station, the control system comprising:
The control system of claim 48, wherein the second switch means also has an OFF position, the control means disengaging the power takeoff shaft when the first switch means is in the ON position and the second switch means is moved to the OFF position.
